BYD Sealion 5 vs Hyundai Kona

What's the difference?

While the BYD Sealion 5 lacks the polish of some more established plug-in hybrids, it has a seriously compelling price advantage over some competitors. It makes a base-model Mitsubishi Eclipse Cross PHEV feel positively outdated and it’s $13,800 cheaper.

BYD's lack of ANCAP rating for the Sealion 5 and the uncertainty around it still being a new brand are downsides, even if BYD is quickly moving past the latter. But being the most affordable PHEV available while having this much showroom appeal is bound to work in the Sealion 5’s favour, just don’t expect a dynamic masterpiece once you’re out on the road.

It’s easy to see why the Hyundai Kona leads the Aussie small SUV category, with this hybrid version enhancing the car’s abilities in key areas. Sharply priced and well-specified, comfortable and practical with a hugely efficient powertrain as well as refined dynamic performance. It’s a compelling package. 

The BYD Sealion 5, from the outside, is inoffensive but also uninspiring. That’s likely not such a bad thing for a mid-size SUV – it’s rare you’re hearing someone talk about how beautiful the Mazda CX-5 or Toyota RAV4 is. 

Its quartet of colour palette options comes in on the safe side, too. Aurora White is standard, Atlantis Grey, Harbour Grey and Cosmos Black are cost-options.

Our test car is Atlantis Grey, which is interestingly quite blue. 

The relatively upright shape is a slight departure from the more ‘aquatic’ silhouettes of BYD’s line-up, but the front grille and light layout are decidedly in step with the brand’s oceanic design language. There’s a bit going on, you could say.

The slimline tail-lights are the rear, especially from a three-quarter angle to the side, look attractive and help break up the rear without looking messy.

The Sealion 5’s design is overall net-good, but it’s inside where the mid-sizer feels like you’re getting plenty for your dollar.

The seats, despite the leather fakery, feel like decent material, and the layout uses buttons and physical controls cleverly without feeling outdated.

The Kona’s exterior mixes smooth curves across its softly rounded nose and swollen haunches with sharp lines and geometric shapes in the lower grille, wheel arches and rear bumper.

And when the current, second-generation version arrived in mid-2023 it swapped out its predecessor’s already slimline LED daytime running lights for an even thinner strip running the width of the car, in similar fashion to the Hyundai Sonata sedan and Staria people mover.

The single line light signature is repeated with the tail-lights, a brake, reversing and indicator cluster confined to the outer rear edges.

Throw in a conspicuous diagonal character line across the doors, and bright metallic accents making a visual connection between the top of the tailgate and the lower edge of the side glass and there’s a lot going on. 

Always a subjective call, but I don’t mind the Kona’s design, although our test car’s ‘Mirage Green’ paint finish leaves me (and my significant other) cold.

Inside, the colour palette is uniformly grey which contributes to a restrained, relatively low-key feel, although light trim for the headliner and pillar covers brightens the mood somewhat.

The dash treatment is cool and contemporary, comprising a wide wrap-around instrument and media screen panel next to a narrow tray on the passenger side.

Fit and finish is impressive and details like perforated centre panels on the leather-faced seats dial up the premium feel.

To actually interact with the interior is, at times, another story. BYD’s tech interface is generally easy to manage, but could be simpler when it comes to navigating menus for the sake of driver distraction.

While larger text and buttons would be welcome, the multimedia system is easy to use when parked, and the functionality is impressive for the price point.

Winning more points for the Sealion 5, though, are the physical controls – buttons and the traditional gear selector – which make the cockpit much more intuitive while on the move.

Ergonomically, though, the adjustment between the steering wheel and driver’s seat could do with some work, as I found it difficult to find a truly comfortable driving position. This is coming from someone 178cm tall, a very normal height in Australia.

Better adjustability on the steering column would be helpful, as it’s something I’m not sure I’d ever get totally used to.

Visibility and physical space inside the Sealion 5 is impressive, though. The car is 4738mm long, 1869mm wide and 1710mm tall, and the roof and window lines don’t swoop too aggressively towards the rear.

There are low window shoulders even into the rear, so light isn’t at a premium, though under-leg support could be better on the pew.

It’s otherwise un-cramped. The 2712mm wheelbase means decent legroom for second-row folk, plus behind the 60/40 split-fold seats there’s 463 litres of space for luggage. That becomes 1410L with the seats folded.

There’s unfortunately no spare tyre, just a tyre repair kit.

Even though the Kona measures a relatively modest 4350mm end-to-end, it offers up copious amounts of interior space. Dr Who would be proud.

Lots of breathing room up front, with the ‘shift-by-wire’ auto transmission shifter’s location on the steering column freeing up extra space in the centre console.

There’s a lidded bin between the seats (the padded top of which doubles as a centre armrest) with an open tray the size of a shoebox in front of it (which includes a pair of swivel-out bottle or cupholders) as well as a wireless phone charging bay ahead of that.

Generous bins in the doors include a recess for large bottles, plus there’s a decent glove box on the passenger side and a handy open tray above it. Plenty of room to keep the bits and pieces of everyday life under control.

Power and connectivity for the driver and passenger runs to two USB-C sockets and a (180W) 12-volt outlet.

Switching to the back is where the Tardis factor steps up a notch, the Kona offering space more in line with a next-size-up medium SUV.

Sitting behind the driver’s seat set to my 183cm position there’s loads of leg and headroom and even enough shoulder room for three adults to get to know one another on shorter journeys. A close to flat floor also helps with foot room in the centre position. Worth noting the rear seat backrests recline slightly for extra comfort options.

No door bins as such but, again, there are recesses for bottles. Netted map pockets on the front seat backs are helpful as is a fold-down centre armrest, which includes a pair of cupholders.

Individual air vents for back-seaters (in the rear of the front centre console) is always a welcome inclusion, and there’s a small oddments tray underneath them. Another pair of USB-C sockets will keep devices charged.

Boot capacity is healthy at a class-competitive 407 litres (VDA), expanding to 1241L with the 60/40 split-folding second row seat folded.

There are storage wells behind the rear wheel tubs, multiple bag hooks and four tie-down anchors to help keep loads secure.

There’s a temporary space-saver spare under the boot floor, which gets a tick over the increasingly common repair kit option and you’ll be able to tow a 1.3-tonne braked trailer (600kg unbraked).

When you’re sitting on top of the sales pyramid, everyone wants a piece of you and it feels like Hyundai has priced and specified the Kona to match the market with some special touches thrown in here and there.

At $39,950, before on-road costs ($44,738, drive-away), the Hybrid Elite’s standard equipment list is generous.

Aside from the safety and performance tech covered further down, big ticket items include leather-appointed seats and steering wheel, heated and power-adjustable front seats (10-way driver / eight-way passenger), 18-inch alloy wheels, LED headlights, tail-lights and DRLs, keyless entry and start, adaptive cruise control and auto rain-sensing wipers.

There’s also dual-zone climate control, digital radio, wireless Android Auto and Apple CarPlay, six-speaker audio, a 12.3-inch multimedia screen and 4.2-inch instrument cluster, rear privacy glass and more. 

A sneaky power tailgate and/or ventilated front seats would be nice at this price-point, but they’re by no means mandatory for the class. 

Similarly priced hybrid rivals like the Haval Jolion Ultra Hybrid ($38,990, drive-away), Honda HR-V e:HEV L ($42,900, drive-away), Subaru Crosstrek Hybrid L ($39,590, before on-road costs) and Toyota Corolla Cross GXL Hybrid ($41,190, before on-road costs) are broadly aligned with the above features list but none of them put the Kona Hybrid Elite in the shade.

The Sealion 5’s front wheels are driven by a combined maximum of 156kW thanks to a 1.5-litre four-cylinder petrol engine (145kW/300Nm) and a permanent magnet synchronous motor (72kW/122Nm).

BYD claims a 0-100km/h sprint of 7.7 seconds for the Sealion 5 Essential, four tenths faster than the Premium despite only a 61kg difference in kerb weight.

The Kona Hybrid is powered by a naturally aspirated 1.6-litre, four-cylinder petrol engine working in concert with a single electric motor, both driving the front wheels through a six-speed dual-clutch automatic transmission.

The all-alloy engine features dual variable valve timing and direct-injection to produce 77kW at 5700rpm and 144Nm at 4000rpm, the permanent magnet synchronous motor chipping in with 32kW/170Nm for a total combined outputs of 104kW/265Nm.

That power output is in the middle of the small hybrid SUV pack and torque is at the higher end. 

Kerb weight is a fraction over 1.5 tonnes and you can expect 0-100km/h acceleration in the high 10-second range with a top speed around 170km/h.

With a charged 12.9kWh lithium iron phosphate (LFP) battery and a full 52-litre (95 RON minimum) fuel tank, BYD reckons the Sealion 5 Essential can cover 1001km under NEDC testing, which is optimistic. It claims 71km can be done on EV power alone.

Not only due to the lenient nature of NEDC testing (WLTP is more common and usually results in lower ranges), but the reality is that once the battery is flat, the engine is doing a lot more work.

Charging is slow, limited to 3.3kW (AC only), which should take between 4 and 5 hours to charge from the lower end of the gauge for the battery size. Given most PHEV owners will do this overnight at home, that’s certainly not the end of the world.

Claimed consumption figures are 1.2L/100km with more than 25 per cent battery charge, or 4.5L/100km when it dips below that.

Realistically you could do sub-50km trips and use no fuel, or never plug your Sealion 5 in and see fuel consumption soar. In any case, anything close to 1001km in a single run is extremely unlikely.

Hyundai’s official fuel consumption figure for the Kona Hybrid Elite, on the combined (urban/extra-urban) cycle is a miserly 3.9L/100km, the 1.6L engine emitting 89g/km of CO2 in the process.

Minimum fuel requirement is 91 RON ‘standard’ unleaded and with a 38-litre tank theoretical range is around 975km.

On test, over several hundred kays taking in city, suburban and freeway running, we saw an average of around 4.4L/100km, which is impressive and a big contributor to the car’s appeal.

Using our real-world test number, the range figure comes in at a still handy 860-plus km.

You might expect a car at this price, regardless of its drivetrain, to be underwhelming from behind the wheel.

That, then, makes it even more pleasantly surprising that the BYD Sealion 5 is actually rather competent. Not massively exciting or dynamic, but certainly not a disappointment.

The Sealion 5 is, save for a couple of arguably minor annoyances, quite easy to get used to and drive.

Firstly, when making proper use of its electric power, the drivetrain provides enough shove for its intended use. It’s not overly powerful, but you won’t have trouble overtaking. It’s the same with most of the inputs, the steering is light but not completely numb – again about right for how the Sealion 5 will be driven.

Perhaps its biggest departure from expectations based on other cars from China is its suspension is on the stiffer side of things, but again it’s not unruly or too rugged. In fact, it does provide a better sense of control than many of its compatriots.

Again, the biggest issue with the Sealion 5 day-to-day is its driving position, the steering column adjustment isn’t up to scratch and there’s not really a perfectly comfortable seating position (I’m a very standard 178cm).

On long trips, you might also find the engine gets quite noisy once the battery power is gone as it works hard to pull the mid-size SUV along under acceleration.

Its driver-assist systems are, you might be pleased to hear, on the calmer side of things – BYD is getting better at calibrating its safety features and I didn’t find myself rushing to switch it all off as quickly as usual.

It can still be a bit too persistent in its lane-keeping, but it’s a big improvement on the way things were.

The first things that come to mind when it comes to driving the Kona Hybrid are comfort, quietness and lack of stress.

From an ergonomic point of view the dash and cabin layout make life easy. There are physical controls for key functions like heating and ventilation, as well as audio and drive modes. Not a fan of the hard driver’s door armrest, though.

The engine is quiet and the transition between combustion and electric power is seamless. It’s fun to watch the (available) graphic screen in the driver’s display illustrating where drive is coming from at any given moment. Without it you’d be hard-pressed to know.

Acceleration is more than adequate and the powertrain’s bias towards electric propulsion means take-offs are ultra-smooth. 

Suspension is by MacPherson-type struts at the front with a multi-link rear set-up and ride quality is outstanding. Despite the Kona Hybrid’s relatively large 18-inch rims, bumps and ruts don’t cause major disruption and the Kumho Ecsta PS71 tyres (215/55) are exceptionally quiet.

Steering accuracy and road feel are both good and drive mode switches between ‘Normal’, ‘Eco’ and ‘Sport’ are noticeable, the latter dialling up urgency and dynamic response.

That said, we found ourselves in Eco most of the time, without any penalty in terms of throttle response or cruising ability.

Torque vectoring helps keep everything buttoned down if you decide to press on through your favourite set of corners, the front seats remain comfy on longer drives while keeping you securely located and the ‘shift-by-wire’ electronic gearshift is slick.

Physical brakes are ventilated discs at the front with solid rotors at the rear and they operate with reassuring smoothness. An active hydraulic booster controls regenerative braking, adjustable through three levels. Warning: the most aggressive setting makes the car annoyingly ‘shunty’ at slower speeds.  

Driver-assist safety tech makes its presence felt occasionally, but never to a disturbing degree… with one exception.

Despite the ability to program a steering wheel button to short-cut directly to the appropriate screen, the need to cancel an incessant and sometimes inaccurate overspeed warning every time you start the car is a pain.

A tidy 10.6m turning circle helps in slow-speed manoeuvres as do front, side and rear parking distance warnings and a high-quality reversing camera.

The Kona Hybrid is as good or better than anything in the class when it comes to the drive experience.

The Kona scored four from a possible five ANCAP stars in 2023, with particularly strong results in Adult Occupant Protection (80 per cent) and Child Occupant Protection (84 per cent).

It features a full portfolio of crash-avoidance tech, including AEB with forward collision warning as well as cyclist, pedestrian and motorcycle detection, plus car-to-car junction, crossing and head-on detection. Phew!  

On top of that, there’s lane-keeping and lane-following assist, blind-spot monitoring, driver-attention warning, rear cross-traffic alert and collision avoidance, ‘Remote Smart Parking Assist’, ‘Safe Exit Warning’, driver fatigue detection, tyre pressure monitoring and more.

If, despite all that, a crash is unavoidable there are seven airbags fitted, including a front centre bag to minimise head clash injuries between driver and co-pilot in a side collision. 

There’s also multi-collision brake (to reduce the chances of subsequent impacts after an initial crash), auto collision notification and an emergency call (SOS) function.

For baby capsules or child seats there are three top-tether points for child seats across the second row with ISOFIX anchors on the two outer positions.

All in all, a comprehensive safety offer that matches or betters the Kona’s class competitors.

BYD has a six-year/150,000km warranty, which is probably more than you’d need in terms of distance but is behind many competitor brands’ timelines – seven to 10 years is becoming the norm, even if it’s conditional.

An eight-year/160,000km warranty covers the battery, which is about par for the industry.

Servicing for the first five proper services ranges from between $285 and $930, plus there's a free check-up six months into ownership and a total cost over the span of $2355 – an average of $471 per service.

BYD has just over 100 dealerships in Australia, so finding one for servicing shouldn’t be too challenging.

The Kona is covered by Hyundai’s seven-year/unlimited-km warranty (upgraded from five years mid-last year), which is ahead of the mainstream five-year warranty pack.

Roadside assistance is complimentary for the first year, with the deal extended for another 12 months every time the car is serviced at an authorised Hyundai dealer. 

Speaking of which, scheduled servicing is recommended every 12 months/10,000km, which is a little lower than the (15,000km) norm for the category. After a complimentary check up at six weeks/1500km, the first seven services (in line with Hyundai’s ‘Lifetime Service Plan Pricing’) come in at $3782, for an average of $540 per workshop visit.

That’s on the high side considering an equivalent Toyota Corolla Cross (in line with ‘Toyota Service Advantage’ pricing) will set you back an average of $354 per service over the same period.

Hyundai has a network of 185 dealers covering every Australian capital, state and territory.
